EU observation mission report on 2017 elections

Presidential elections held on 20 March: “The STAE concluded the municipal tabulation well before the 48-hours deadline. Subsequently, the CNE completed the national tabulation within the legal deadline and presented provisional results on 25 March. Since no appeals were lodged within 24 hours after the publication of the provisional results, the CNE submitted the dossier to the Court of Appeal which validated the results, and on 30 March declared Francisco Guterres Lú-Olo, with 57,1 % of valid votes, winner of the 2017 presidential election.”

Legislative elections held on 22 July: “The provisional national results were published on 27 July, and were not contested within the legally established 48-hour period. Consequently, the Court of Appeal proclaimed the final results on 1 August.”
